WebJun 1, 2024 · The global wavelet spectrum and the PSD show higher spectral covariance in the ~23 kyr periodicity. Moreover, the phase (arrows in the central panel and black line … WebThis wavelet bias problem is addressed in Liu et al. [2007]. It is demonstrated that a physically consistent definition of energy for the wavelet power spectrum should be the transform coefficient squared divided by the scale it associates. Thus, a bias rectification is proposed, i.e., the wavelet power spectrum should be divided by its scales.
